Bidallies via eBay offers the refurbished Unlocked Apple iPhone X 64GB GSM Smartphone in Silver or Space Grey for $599.99 with free shipping. That's tied with our mention from a month ago as the lowest outright price we've seen. (It's the best deal for a refurb now by $131.) It has an A11 Bionic chip neural engine, 12-megapixel dual rear camera with dual OIS, wireless charging, and Bluetooth 5.0. No warranty information is provided, but a 30-day return policy applies.
